adopt a form of integrated circuit board, and can include
conventional functional modules such as current detection module,
voltage detection module and control chip; the control chip can
integrate a plurality of protection functions and a driving
function of the light-emitting apparatus 20. For example, an
electric current in the conducting circuit 113 can be obtained from
the current detection module by the control chip; when the current
is excessively large, turning off the conducting circuit 113 to
achieve an overcurrent protection of the light-emitting apparatus
20. For example, a voltage applied on the first conducting terminal
1131 can be obtained from the voltage detection module by the
control chip; when the voltage is excessively small, turning off
the conducting circuit 113 to achieve an over-discharge protection
of the power supply module 30 in the case where a DC battery pack
is used as the power supply module 30. For example, a current value
of the conducting circuit 113 can be regulated by the control chip,
so that the light-emitting apparatus 20 can be operated at a rated
operational current. In a practical application, the control module
1133 can achieve turning on and off the conducting circuit 113 by
adjusting an on-state and an off-state of the on-off switch
1134.
In an example of the preset disclosure, the second conducting
terminal 1132 can be directly disposed at an end of the control
module 1133 located inside the light source mounting part 112; the
light-emitting apparatus 20 has an engaging interface (not
illustrated) which is electrically connected to both of the
light-emitting source and the driving component in the
light-emitting apparatus 20; when the light-emitting apparatus 20
is mounted to the light source mounting part 112, the engaging
interface of the light-emitting apparatus 20 is electrically
connected to the second conducting terminal 1132. In a practical
application, the engaging interface and the second conducting
terminal 1132 can adopt various forms such as abutting electrode
pieces, contacting dots, engaging chute and long straight metallic
rod, without particularly described herein.
The on-off switch 1134 can include: a switch base 11341 connected
to the conducting circuit 113 in series, and a switch button 11342
connected to the switch base 11341. Specifically, the switch base
11341 is connected to the integrated circuit board on which the
control module 1133 is located through two independent pins 11343,
so that the switch base 11341 and the control module 1133 are
connected in series. The switch button 11342 can be pressed towards
the switch base 11341 to turn on the switch base 11341; when the
switch button 11342 is no longer pressed, it moves away from the
switch base 11341 and returns to its original position, so as to
turn off the switch base 11341, thereby achieving turning on and
turning off the conducting circuit 113 by operating the on-off
switch 1134. In a practical application, the switch base 11341 is a
base of a commonly used micro switch, and then the switch button
11342 can be a trigger button of the micro switch.
Of course, in a practical application, when the adaptor 10 has a
relatively great size and results in a relatively large distance
among the first conducting terminal 1131, the second conducting
terminal 1132, the control module 1133 and the on-off switch 1134,
the conducting circuit 113 can further include a conducting wire
(not labeled) which connects the first conducting terminal 1131,
the second conducting terminal 1132, the control module 1133 and
the on-off switch 1134 in series; the conducting wire can be made
of a conventional enameled copper wire or enameled wire, and can
also be made of a hard metallic conductor, as long as it satisfies
a basic requirement of achieving current transfer. The conducting
wire can be electrically connected to the first conducting terminal
1131, the second conducting terminal 1132, the control module 1133
and the on-off switch 1134 by a fixed connection method such as
welding, press-fitting and insulating displacement contacting, or
by an adaptor interface such as FFC and FPC.
When the power supply module 30 is engaged with the power supply
mounting part 111 and when the light-emitting apparatus 20 is
engaged with or integrally provided with the light source mounting
part 112, the power supply module 30 is electrically connected to
the first conducting terminal 1131 in the conducting circuit 113,
the light-emitting apparatus 20 is electrically connected to the
second conducting terminal 1132 in the conducting circuit 113, so
as to achieve transferring the electric power outputted by the
power supply module 30 to the light-emitting apparatus 20.
As illustrated in FIGS. 5 and 6, the protruding part 12 is movably
connected with the main body 11, and is configured for safety
protection during a mounting process of the main body 11 and the
power supply module 30, so as to satisfy a safety standard
requirement. In an example of the present disclosure, the
protruding part 12 includes a first portion and a second portion
both extending along the longitudinal lengthwise direction D1 of
the main body. The first portion and the second portion are
perpendicularly connected so that a cross section of the protruding
part 12 taken along a direction perpendicular to the longitudinal
lengthwise direction D1 has a shape close to T shape.
The protruding part 12 can be operatively moved to a blocking
position and a releasing position. When the protruding part 12 is
in the blocking position, the protruding part 12 blocks the power
supply mounting part 111 from being engaged with the power supply
module 30; when the protruding part 12 is in the releasing
position, the protruding part 12 releases the power supply mounting
part 111 to engage with the power supply module 30.
It should be noted that, "the power supply mounting part 111 is
engaged with the power supply module 30" described herein is used
for specifying the case where the power supply mounting part 111 is
mechanically connected with the power supply module 30 and the
conducting circuit 113 is electrically connected with the power
supply module 30, but not including the case where the power supply
mounting part 111 is mechanically connected with the power supply
module 30 but the conducting circuit 113 is not electrically
connected with the power supply module 30.
For example, the light-emitting apparatus 20 and the adaptor 10 can
be integrally provided to form an independently usable light source
device. Due to the presence of the protruding part 12, when it has
no need of mounting the light source device to the power supply
module 30, a user can move the protruding part 12 to the blocking
position so that the adaptor 10 has no way of being engaged with
the power supply module 30, which prevents the user from engaging
the adaptor 10 in the light source device with the power supply
module 30 without any protection measure by mistaken and resulting
in an electric shock of the user, thereby ensuring the safety of
the user and allowing the lighting apparatus 100 to meet the safety
standard requirement. Conversely, when it needs to mount the light
source device to the power supply module 30, the user can move the
protruding part 12 to the releasing position so that the adaptor 10
can be engaged with the power supply module 30, which allows the
lighting apparatus 100 to be normally operated.
In a practical application, the protruding part 12 can extend along
the longitudinal lengthwise direction D1 of the main body 11 and is
movable along this direction. When the power supply mounting part
111 is engaged with the power supply module 30, the protruding part
12 originally in the blocking position can be moved towards the
releasing position by the power supply module 30, so as to allow
the first conducting terminal 1131 to be electrically connected to
the terminal connecting part 33 in the power supply module 30, and
to allow the user to accomplish both of adjusting a position of the
protruding part 12 and subsequently engaging the power supply
module 30 with the adaptor 10 by one single step, thereby improving
the user experience.
Before the power supply mounting part 111 is engaged with the power
supply module 30, an annular retaining wall 31 in the power supply
module 30 is moved to a position where a recess 32 is exposed and a
terminal connecting part 33 is covered. When the power supply
mounting part 111 is mounted to the power supply module 30, the
protruding part 12 in the blocking position enters the recess 32,
and the first conducting terminal 1131 cannot engage with the
terminal connecting part 33 because the terminal connecting part 33
is covered by the annular retaining wall 31, thus it needs to
rotate the adaptor 10 around the longitudinal lengthwise direction
D1 thereof inside the power supply module 30. Because an end of the
protruding part 12 is provided with a guiding slope, the protruding
part 12 is moved towards the releasing position with the guide of
the guiding slope and leaves the recess 32; subsequently, when the
protruding part 12 is moved to be flush with the annular retaining
wall 31, the annular retaining wall 31 is driven to rotate, so that
the terminal connecting part 33 is exposed to the outside, and the
first conducting terminal 113 can be engaged with the terminal
connecting part 33.
Of course, in other example(s) of the present disclosure, it's also
possible to allow the first conducting terminal 1131 to be engaged
with the terminal connecting part 33 by means of directly pushing
the protruding part 12 to be moved towards the releasing position
along the longitudinal lengthwise direction D1, which is well-known
technique for those ordinary skilled in the art, without
particularly described herein.
In an example of the present disclosure, the adaptor 10 further
includes an elastic member 14 located between the main body 11 and
the protruding part 12. The elastic member 14 can be a spring. The
elastic member 14 is configured for providing the protruding part
12 with an acting force when the protruding part 12 is in the
releasing position, to move the protruding part 12 towards the
blocking position. Due to the presence of the elastic member 14,
the protruding part 12 always has a tendency of moving towards the
blocking position, so that the protruding part 12 can automatically
return to the blocking position when the adaptor 10 is separated
from the power supply module 30. Specifically, when the adaptor 10
is engaged with the power supply module 30, the protruding part 12
is subjected to a resisting force from the power supply module 30,
and is moved to the releasing position and maintains in the
releasing position; the operating component 13 is moved to the
on-position to turn on the conducting circuit 113. When the adaptor
10 is separated from the power supply module 30, the elastic member
14 being compressed provides the protruding part 12 with an acting
force which moves the protruding part 12 towards the blocking
position, so that the protruding part 12 rebounds to the blocking
position from the releasing position; during this process, the
operating component 13 is driven to move from the on-position to
the off-position, so as to turn off the conducting circuit 113.
In an example of the present disclosure, the main body 11 includes
an outer wall 114 and an inner chamber 115 enclosed by the outer
wall 114; the power supply mounting part 111 and the light source
mounting part 112 both are provided on the outer wall 114, and the
conducting circuit 113 is received in the inner chamber 115.
The operating component 13 is located on the outer wall 114, and is
operatively movable on the outer wall 114. In a practical
application, the main body 11 further includes a sliding groove 116
located on the outer wall 114, the operating component 13 is
movably located in the sliding groove so as to switch between the
on-position and the off-position. Depending on different layout of
the sliding groove, the operating component 13 with different
motion tracks can be obtained. For example, the sliding groove 116
can extend along the longitudinal lengthwise direction D1 of the
main body 11, and then the operating component 13 can also be
movable along the direction D1, so that when the adaptor 10 held by
the user is engaged with power supply module 30, the operating
component 13 can be prodded with a thumb along a curved direction
of the thumb, which makes an operation of the operating component
13 more ergonomic, thereby improving the user experience.
Of course, the operating component 13 may not move along the
direction D1, for example, the operating component 13 can move on
the main body 11 spirally or rotatably; the operating component 13
even can be a button or the like, without particularly described
herein.
In an example of the present disclosure, the operating component 13
includes a pushing part 131 movable in the sliding groove 116 on
the outer wall 114, an extension part 132 connected to the pushing
part 131, and a locking protrusion 133 located on a surface of the
pushing part 131 facing the sliding groove 116; a surface of the
pushing part 131 is configured to be rough so that it's convenient
for the user to push. An extension direction of the extension part
132 is directing to the inner chamber 115 of the main body 11 from
the outer wall 114 of the main body 11.
The sliding groove 116 is provided with a locking recess 1161.
During the movement of the operating component 13, the locking
protrusion 133 will enter the locking recess 116 so that positions
of the operating component 13 and the main body 11 are fixed, i.e.,
the operating component 13 is locked with the outer wall 114 of the
main body 11. In this case, the protruding part 12 is in the
releasing position, and the operating component 13 is in an
on-state. Subsequently, it only needs to push the locking
protrusion 133 of the operating component 13 to leave the locking
recess 1161, so that the operating component 13 is unlocked from
the outer wall 114 of the main body 11, i.e., allowing the
protruding part 12 to be released from the releasing position and
moved to the blocking position under the action of the elastic
member 14, and meanwhile driving the operating component 13 to move
to the off-position.
With reference to FIGS. 6 and 7, the protruding part 12 includes an
operating component receiving chamber 121, and the extension part
132 of the operating component 13 extends into the operating
component receiving chamber 121. With the movement of the operating
component 13, the extension part 132 will be interfered with the
retaining wall 1211 at a periphery of the operating component
receiving chamber 121.
In an example of the present disclosure, with the movement of the
operating component 13 in the sliding groove 116, the operating
component 13 can move to the on-position and the off-position. When
the locking protrusion 133 of the operating component 13 enters the
locking recess 1161 of the sliding groove 116, the operating
component 13 is locked with the outer wall 114, and the operating
component 13 is in its on-position; in this case, the extension
part 132 of the operating component 132 is interfered with the
retaining wall 1211 of the protruding 12, and hence to lock the
protruding part 12 in the releasing position; when the locking
protrusion 133 of the operating component 13 is separated from the
locking recess 1161 of the sliding groove 116, the extension part
132 of the operating component 13 no longer can be interfered with
the retaining wall 1211 of the protruding part 12, and then the
protruding part 12 is released from the releasing position and
moved towards the blocking position; subsequently, the operating
component 13 is abutted against an edge of the sliding groove 116
through the pushing part 131 thereof, so that the extension part
132 of the operating component 13 is interfered with the retaining
wall 1211 of the protruding part 12, again, to limit the protruding
part 12 in its blocking position.
When the operating component 13 is in the on-position and the
off-position, it cannot only play a role of limiting the position
of the protruding part 12 but also can turn on or turn off the
conducting circuit 113. Specifically, when the operating component
13 is in the on-position, the operating component 13 turns on the
conducting circuit 113; when the operating component 13 is in the
off-position, the operating component 13 turns off the conducting
circuit 113.
In a practical application, the conducting circuit 113 can be
turned on and turned off by the operating component 13 moving to a
position above the on-off switch 1134 in the conducting circuit 113
and by the operating component 13 cooperating with the on-off
switch 1134. Specifically, by arranging the position of the
extension part 132 of the operating component 13 and the position
of the on-off switch 1134, when the operating component 13 is in
the on-position, the extension part 132 is located above the switch
button 11342 of the on-off switch 1134 and press the switch button
11342 towards the switch base 11341 so as to turn on the on-off
switch 1134, thereby achieving turning on the conducting circuit
113. Correspondingly, when the operating component 13 moves from
the on-position to the off-position, the extension part 132 leaves
the position above the switch button 11342, and the switch button
11342 moves far away from the switch base 11341 and returns to its
original position, so that the on-off switch 1134 is turned off,
thereby achieving turning off the conducting circuit 113.
In a practical application, the adaptor 10 includes an elastic
pressing piece 15 movably connected to the main body 11. The
elastic pressing piece 15 is located inside the inner chamber 115,
and the extension part 132 of the operating component 13 can press
against the elastic pressing piece 15 to move the elastic pressing
piece 15 towards or away from the switch button 11342 of the on-off
switch 1134, so as to turn on and turn off the on-off switch 1134
by pressing the switch button 11342 towards the switch base 11341
and by releasing the switch button 11342.
In a practical application, the elastic pressing piece 15 can
include a fixing part 151 connected to the switch base 11341 of the
on-off switch 1134, and a cantilever part 152 elastically connected
to the fixing part 151; the cantilever part 152 extends to be above
the switch button 11342. When the cantilever part 152 is not
subjected to an external force, it is suspended above the switch
button 11342 without pressing against the switch button 11342;
subsequently, with the movement of the operating component 13, the
extension part 132 of the operating component 13 presses against
the cantilever part 152 and moves the cantilever part 152 towards
the switch button 11342, and hence pushes the switch button 11342
towards the switch base 11341, so as to turn on the on-off switch
1134. Subsequently, with the movement of the operating component 13
which releases the cantilever part 152, the cantilever part 152
will return to its original position under an elastic force of the
cantilever part 152 itself, and will be suspended above the switch
button 11342 again.
By turning on and turning off the on-off switch 1134 through
disposing the elastic pressing piece 15, it has no need of
precisely setting the position of the extension part 132 of the
operating component 13 and the position of the switch button 11342;
thus the switch button 11342 still can be pressed and released even
if the operating component 13 is in the on-position and the
extension part 132 has not moved to the position above the switch
button 11342 yet, which reduces a difficulty in manufacturing the
adaptor 10.

lighting apparatus 100 provided by the examples of the present
disclosure, the adaptor 10 is provided with the protruding part 12
and the operating component 13 which are relatively fixed, the
protruding part 12 can be moved to the blocking position for
blocking the power supply mounting part 111 from being mounted to
the power supply module 30 and to the releasing position for
releasing the power supply mounting part 111 to be mounted to the
power supply module 30; when the adaptor 10 is engaged with the
power supply module 30, the protruding part 12 subjected to a
resisting force from the power supply module 30 is moved to the
releasing position and maintains in the releasing position, and the
operating component 13 is moved to the on-position so as to turn on
the conducting circuit 113; when the adaptor 10 is separated from
the power supply module 30, the protruding part 12 is moved from
the releasing position to the blocking position and meanwhile
driving the operating component 13 to move from the on-position to
the off-position so as to turn off the conducting circuit 113,
which prevents the user from activating the lighting apparatus by
misoperation and resulting in an electric shock, thereby improving
the safety of the lighting apparatus. Furthermore, the lighting
apparatus can be quickly assembled and turned on when it demands to
use the lighting apparatus.
